The Swarm's Infestation

Deathtouch, Menace
When The Swarm's Infestation enters the battlefield, sacrifice a creature. You gain life
equal to twice the sacrificed creature's power.
When The Swarm's Infestation deals combat
damage to a player, all creatures that player
controls get -X/-X until the end of the turn,
where X is equal to The Swarm's Infestation's
power.
